THE USE OF COMPACTED SOIL-CEMENT IN WATER CONTROL STRUCTURES

The use of compacted soil-cement for upstream slope protection of dams and its use for other water control structures began in 1951 with the construction of an experimental test section at the Bonny Dam Reservoir Colorado, by the U.S. Bureau of Reclamation. After a watching and waiting period of 10 years, during which time the results of the test were encouraging, the first soil-cement dam facing was specified for Merritt Dam, Nebraska in 1961. Since that time, 41 dams have been built in the United States where the upstream slope protection consisted of soil- cement usually constructed in layers, stair-step fashion. In addition, 23 dikes and embankments involving nearly 1 million cubic yards (750,000 m to third power) of compacted soil-cement have been built to contain large reservoirs and protect highway, railroads and towns located adjacent to the reservoirs. Compacted soil-cement also has been used for many other types of water control structures. These include water storage reservoirs which are lined on the bottom and have embankment slope protection, small auxiliary spillways, protection along rivers, dam diversion channels, tailraces, and foundation replacement for stabilization purposes. Recently, extremely large volumes of compacted soil-cement facings, or dikes made completely of soil-cement, have been constructed in connection with thermal power plants for storage and cooling water requirements. The performance of dams and other embankments and channels faced with correctly designed and well compacted soil-cement has been excellent and, with one exception, little or no maintenance has been required. When severe wave action is anticipated, consideration must be given to using the most suitable sandy soils for the soil-cement with adequate cement contents. Particular care should be given to adequate bonding between the layers of the compacted soil-cement. Good construction control is important for all soil-cement construction work involving water control structures.
